It’s an isoceles triangle so 180-64=116degrees = the sum of the other two equal angles in the triangle QRP and so angle QRP is 116÷2=58degrees, angles QRP and SRT are vertically opposite so they’re equal. The triangle SRT is also isosceles so 180-58= 122degrees = the sum of the last two equal base angles (including RST that you want to find) So lastly do 122÷2= 61degrees = angle RST

Step-by-step explanation:
Answer:8
Step-by-step explanation:
Use Pythagorean Theorem
c2 = a2 + b2
152 = a2 + 12
a2 = 152 - 122
=225 - 144 = 81
a = 9 ft
Distance from base of antenna = 9ft
Answer:
The percentage rate per annum is 2.8%
Step-by-step explanation:
We need to multiply the principal by the time, then divide the interest by the product of P×T, so:
1,600 × 5 = 8,000
224 ÷ 8,000 = 0.028
Then we convert our final product to a percentage.
0.028 to a percent is 2.8%
